Affiliates can link directly to a pre-join page by appending
/join to a linkcode. For example:
http://linkdomain/track/MjozOjE/join
Affiliates can link to any other page on your site by appending a forward-slash and a relative URL to the link code. For example, using the following linkcode to link to http://example.com/tour1.html:
http://join.example.com/track/MjozOjE/tour1.html
Affiliates can manipulate the query string too. For example, the affiliate can pass the variable, extra_var=1234 to a tour by appending a question mark and the variable assignment to their linkcode:
http://join.example.com/track/MjozOjE/?extra_var=1234
